Серия докладов про "другую" автоматизацию, в которых рассмотрим альтернативы привычным WEB UI / API test automation. В первой части проговорим, что такое Embedded System и как автоматизируют тестирование встраиваемых систем.

1. Если UI/API автоматизация
уже не штырит…

3. Agenda:
•Short introduction
•Testing in terms of ES
•Detailed example – car
EPAS ECU

4. Embedded System
Is a combination of computer
hardware and software,
designed for a specific function or
functions within a larger system.

5. Key characteristics:
Hardware + software
Designed for a specific task
Based on SoC solutions

6. Examples

7. Examples

8. Applications
Almost every single mechanical or electrical device in the world
will feature at least one embedded system.

9. Testing in Terms of Embedded Systems
 Validation & Verification is important part of
development process
 Strict and careful testing is crucial to grant
software certification
 Mature processes are must for successful projects
